[libcxx-commits] [PATCH] D122092: [libc++] `bitset::operator[] const` should return bool

[Richard Smith - zygoloid via Phabricator via libcxx-commits]

rsmith added a comment.

Is it intentional that this leaves `std::vector<bool>::const_iterator::reference` as the class type? We're seeing some breakage in `absl` due to that.

We're also seeing some breakage due to the result of `std::bitset::operator[]() const` no longer being convertible to `std::bitset::const_reference`, which would at least have been easier to understand if the `const_reference` typedef were removed entirely.
